The FeCl 3 method is a well-established method to polymerize thiophenes [30±46] and even polydeuterated PATs [47] and continues to be the most widely used and straightforward method to prepare PT and its derivatives, despite the limitations and drawbacks to the method.…”

Directing the structure and function of polythiophenes (PTs) can lead to remarkable enhancements in the electronic and photonic properties of the resultant materials, as discussed in this comprehensive review of the chemistry and synthesis of PTs. The Figure illustrates the use of heteroatom‐functionalized PTs as chemical sensors: upon ion complexation PT conjugation is greatly reduced, leading to a sensory response.

“…Taka et al [93,94] have compared the soluble and insoluble polymerization products of P30T. The insoluble part is assumed to resemble the thermally dedoped, degenerated polymer but no significantly large differences between the soluble and the insoluble parts can be seen in the NMR and XPS spectra and the interpretation of the results is still open.…”

ABSTRACf. The poly(3-alkylthiophenes) represent a new generation of conducting polymers, that exhibit both solution and melt processability. These properties open new possibilities for the utilization of conducting polymers in practical applications. Furtheonore, the solubility of these polymers enables the characterization of the physical and chemical structure in greater detail than hitherto have been possible. In this chapter we give a brief review of the synthetic routes to the poly(3-alkylthiophenes) as well as an overview of some of the recent results on the physical and chemical characterization of this class of materials. In this overview we include results on stability properties, transport properties, thermo-and solvatochromism. We also discuss some aspects of the utilization of the poly(3-alkylthiophenes) in applications.

Conductive polymers can stimulate the adhesion and proliferation of several cell types being an interesting material to be applied in the field of tissue engineering. In this application, the addition of a thermosensitive polymer has been pointed out as an attractive strategy to improve mechanical strength and to provide conformation changes at temperature close to human body temperature. The main goal of this work was to evaluate the physical–chemical properties and promotion of cell proliferation and possible application as scaffolds for tissue engineering of blends of poly(N‐vinylcaprolactam) (PNVCL) and poly(N‐vinylcaprolactam‐co‐butylacrylate) (PNVCL‐co‐ABu) with poly(3‐hexylthiophene) (P3HT). Both polymers were synthesized and their chemical structures were confirmed by Fourier Transform Infrared (FT‐IR) and nuclear magnetic resonance (NMR) analyses. The materials were processed in films form for structural characterization, impedance measurements, and thermogravimetric analysis. The in vitro biological assays were performed using the materials as electrospun mats. The FT‐IR was also used to characterize the blends. The addition of P3HT did not change thermal stability and showed low conductivity values of the blends. Comparing the in vitro behavior of the blends and the polymers it was possible to conclude that the presence of P3HT improved cytocompatibility and promoted cell proliferation.
